DECK-CLEANING MACHINE.

SPECIFICATION forming part Of Letters Patent N0. 478,443, dated July 5, 1892.

Application filed May 26, 1891. Serial No. 394,232.- (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL LOWBERG, of New York city, in'the county and State of New York, have invented a new and Improved Deck-Cleaning Machine, of which the following is a full, clear, and exact description.

My invention relates to an improvement in deck-cleaning machinesor machines for holy-stoning a deck, and has for its object to provide a machine of, simple, durable, and economic construction wherewith the holystones may be moved across the surface of the deck in frictional contact therewith and in any direction desired; and another object of. the invention is to provide for rotating the stones and permitting them to rest freely upon the deck and feedby gravity.

A further object of v the invention is to so construct the machine that it may be steered in any desired direction, and wherein water and grinding material may be supplied to the leek in the path of a stone as required.

The invention-consists i11 the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a' part of this specification, in which similar figures and'letters of reference indicate corresponding parts in all the views.

Figure Us a side elevation of themachine, partly in section. Fig. 2 is a plan view of the stone-carrying frame, illustrating the stones in position therein. Fig. 3 is a front elevation of the machine. Fig. 4: is a rear elevation thereof, and Fig. 5 is a detail perspective view.

The frame of the machine usually consists of upper and lower horizontal beams and 11, united byhorizontal cross-beams '12 and perpendicular side beams 13. At the rear of the frame bearings 14: of any approved construction are secured to the bottom, in which bearings an'axle 15 is held to revolve, the said axle having secured'to its extremities supporting-wheels l6, and between the bearings ratchet-wheels 17 and 18, having their teeth inclined in opposite directions, are firmly at- 50 tached to the axle. The forward axle 19 has attached thereto an upwardly-extendingyoke 20, and supporting-wheels2l are loosely mounted upon-the extremities of the axle. The yoke 20 is attached in any suitable or approved manner to a vertical shaft 22, which is held to turn in the-frame, and the upper end of the shaft usually extends to and beyond the upper surface of the frame and is provided witlran attachedcrank-arm 23- whereby the shaft is revolved, the said crankarm being adaptedto engage with a suitable rack 24 or the equivalent thereof. By means of the crank-arm 23 and the shaft 22 the machine may be steered in any desired direction.

At or near the center of the frame, upon the top thereof, a shaft 25 is transversely journaled in suitable boxes, which shaft is provided with two crank-arms 26 and 27, one being at a right angle tothe other. Near the rear of the frame uprights 28 are secured to its upper portion, one at each side, and the uprights are connected at or near their upper ends bya fixed shaft 29. Upon the shaft 29 two walking beams 30 and 31 are loosely mounted. The walking-beam 31 is connected with. the crank-arm 26 by a link 32, and the walking-beam 30 is connected by a link 33 with the crank-arm 27 of the shaft 25.

The crank-shaft 25 is provided with an attached bevel-gear 34, which bevel-gear meshes with a bevel-pinion 35, secured to the upper end of a vertical shaft 36, the said shaft being journaled in suitable supports in the frame. The shaft 36 extends downward below the frame and is attached to a stone-carrier A. (Illustrated in detail in Fig. 2.) The stonecarrier consists of a skeleton frame containinga number of pockets 37, extending through from the upper to the lower face. Ordinarily the stone-carrier A is constructed of a circular band 38, which is connected with a central hub 39 bya series of spider-like arms 40, and the pockets are ordinarily made angular at one end and curved at the opposite end. The

pockets 37 are adapted to receive the polish:

ing-stones 41, ordinarily termed holy-stones. The stones are loosely fitted in the pockets and extend above and below the carrier, as is illustrated in Fig. 1. Thus as their under surfaces engaging with the deck are worn away the stones feed downward by gravity.

\Vithin the bodyof the machine two tanks 42 and 43 are preferably located, one containing an abrasing material and the other a liquid, and each tank feeds its contents in suitable proportions and at proper times in the path of the holy-stones. This feeding may be accomplished in any suitable or approved manner. In the drawings pipes 44 and 45, containing suitable valves, are represented as leading from the tanks and as carried at one side of the stones. It will be observed that when the walking-beams are rocked upon the shaft 29 through the medium of the crankshaft 25 a rotary motion is imparted to the vertical shaft 36,and consequently a like motion is given to the carrier containing the holy-stones.

The machine is carried forward and backward, as occasion may require, through the medium of dogs 46 and 47, engaging the ratchet-wheels 17 and 18 on the rear axle. The dogs are oppositely located and alternately engage the ratchet-wheels, the dog 47 engaging the ratchetwheel 17 and the dog 46 the ratchet-wheel 18. The upper ends of the dogs areadj ustably and pivotally attached to levers 48, fulcrumed upon the frame at the rear thereof, as is best shown in Fig. 1. The levers contain a series of apertures for the adjustment of the dogs, and the inner ends of said levers are pivotally connected by links 49 with the walking-beams 30 and 31 at the rear of the fulcrum of the latter, the links 32 and 33, uniting the walking-beams with the crank-shank 25, being located some distance in front of their fulcrums.

The dogs 46 and 47 consist of rods passing downward through suitable recesses in the frame and engaging with the ratchet-wheels by gravity. The lower end of each rod is enlarged and is provided with a recess 50, preferably rectangular, the lower Wall of the recess being inclined, and when a dog is in engagement with a ratchet-wheel the teeth of the latter enter the recess in the former and the inclined base-wall of the recess engages with one of the teeth, and as the walkingbeams are manipulated to operate the stones the dog in engagement with a ratchet-wheel will be elevated and said wheel turned, imparting a rotary movement to the rear axle 15, and according to which dog of a sctis made to engage with the ratchet-wheels is the machine propelled rearward or forward. The length of the forward or rearward travel of the machine is determined by theadjustment of the dogs upon the levers 48, causing the recesses in the dogs to receive a greater or a less number of teeth of the ratchet-wheels. One dog of each set is held out of engagement with the ratchet-wheels in any suitable or approved manner.

It is evident that the machine is exceedingly simple and durable in construction, and

that a deck by its use may be thoroughly cleaned in a much more expeditious manner than heretofore and by the employment of fewer hands.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a machine for cleaning decks and like surfaces, the combination, with a wheeled frame and a stone-carrier located beneath the frame, of a drive-shaft provided with crank arms having a gear connection with the stone carrier, walking-beams having a pitman connection with the crank-arms of the driveshaft, and means for propelling the frame from the walking-beams, as and for the purpose specified.
